A simple build.

No xml editing (including the overload api) except the control surface integrations.
Which mean all parts without an in-game UI editor are stock size and mass, and those parts that do have an in-game UI editors, fuselage and wings, are within the bounds set by their editor.

This thing WILL tip over on takeoff and landing, because, while the landing gear appears to have two wheels, the physics model only represents a single wheel.

I should also mention, this design is quite unrealistic. Mostly due to the intake design...boundary layer...cough...cough...And let's not mention you can't just stick a high bypass turbofan into the fuselage...The tail booms are probably too close to the jet blast too...

But anyways, it can go about 2800 knots at 66000 ft, and 1150 kts at sea-level (20 ft).
